Description of the bug

I don't exactly know if this is a bug, but I have no idea how to verify it or fix it. I was using XFCE for some time and I have this box for example:
(box :width 140 :height 65 :style 'background-image: url("https://steamcdn-a.akamaihd.net/steam/apps/379430/header.jpg"); background-size: 100%' )
In XFCE it was working correctly, image was loaded and displayed. Now I switched to i3 (nixos system) and images are gone. I suspect I am missing some package, service, library, something that was present on XFCE and is not present in i3, but I have no idea what. I tried to install all packages listed on eww pages, but still no change

Reproducing the issue

• install clean i3 system
• create some box widget with background-image from url
• run that widget

Expected behaviour

Images should be loaded and displayed

Additional context

No response

I managed to get around it with script that downloads files locally and using image widget, but still have no idea why is not working with that bacground-image

reproducible on my nixos system, image does not show up.
were you using xfce on nixos as well?

Yes, also on nixos as well. Pretty much same configuration as with i3, don't know about anything special that would allow images to load. Must be something bundled with xfce I think

Out of curiosity I tried also on nixos + hyprland, same problem there

i am currently using hyprland on nixos.
i sadly dont really have the time to investigate this right now, sorry.
however, i'll gladly test things if someone else picks this up!
